I have a couple of 550 size motors for sale that I no longer need. First is a Gaui branded Scorpion 4020-910kv motor that was used in my Logo 500 for about 25 flights. It will work ok on 6s but is better and more suited for 8s. The motor runs smooth and the bearings feel good, they were oiled just about every ten flights. Second motor is a Century 600 Plus that was also used in my Logo. It was used for about 30 flights and the bearings are still smooth. Both motors are in good shape, the Scorpion seems to have a little of the anno wore off on the bottom but besides that it is in good shape. I will ship these motors USPS priority mail and cover shipping and PP fee's in the US only.
I am asking $80 shipped for the Scorpion motor and $45 shipped for the Century motor.
